I finally got around to assembling and testing the EMG amplifier circuit boards. After fixing a design mistake with the board, I was able to get solid readings out of all four boards. The design mistake was a fairly obscure one, but provided me with a valuable learning experience. Schematic and Layout For the amplifier components, I used a … More Assembly and Testing of the SMD-EMG Amplifier
The EMG circuit boards have finally arrived. The boards were ordered from http://www.4pcb.com as part of their 2-layer special deal. I’m impressed with how they turned out! Unfortunately, my shipment of parts was somehow lost, so I’m waiting on the reshipment to arrive. Once the parts arrive I get to test my surface mount soldering … More The EMG PCB has arrived!
Introduction In this post, I showed you how to build a low cost EMG amplifier. While that amplifier design works perfectly fine, I mentioned that there were quite a few issues that could be improved upon. These include: Replacing the op-amp instrumentation amplifier with an instrumentation amplifier IC. Not only will this give better performance because … More Improving the EMG Amplifier
Attention: I have since improved upon this circuit. Version 2 is covered here. Introduction If you are a Star Wars fan like me, you probably wish that the Force was real so you could manipulate objects without touching them. What if I told you that the Force actually did exist and you had the ability to control … More Control anything using your muscles – How to build an EMG amplifier
